Deepfake video of Facebook CEO Mark Zuckerberg posted on Instagram

The Zuckerberg video was posted four days ago. Now, the tables have turned, and someone has posted a deepfake video of Facebook CEO Mark Zuckberberg on Instagram. First reported by Vice, the video shows Zuckerberg giving a sinister-sounding speech about the power of controlling data, while attributing it all to "Spectre".

"Imagine this for a second: One man, with total control of billions of people's stolen data, all their secrets, their lives, their futures", he appears to say.

The video of Zuckerberg manipulates an actual statement from the CEO, and refers to Facebook's recent controversies over both stolen user data and one such manipulated video.

Zuckerberg and other Facebook officials have said that artificial intelligence technology will ultimately allow the company to control the spread of false information, but the doctored video of Pelosi showed disagreement among big social media companies on what is worthy of removal.

The other week Facebook came under fire when they refused to remove a doctored video of Speaker of the House Nancy Pelosi, which made her appear drunk and out-of-it, that had been shared by many right-wing figures, including the president of the United States. The video was a "deepfake", a technique that uses AI to create videos of people saying something they didn't, highlighting the challenges social networks face when it comes to policing manipulated content. Zuckerberg called Pelosi but she wasn't "eager" to hear what he had to say, The Washington Post reported on Tuesday. The video, titled "A World Without Facebook", was viewed more than 32 million times, but it's now unavailable.

Until recently, video hoaxes were relatively rare since they are harder to pull off than fakes of still images, but this is changing rapidly thanks to the rise of GANs, or generative adversarial networks. Ben-Ami told Motherboard that engineers used a 21-second clip of Zuckerberg from a seven-minute video to train the AI model.

It took about a day to make an initial version of the video with one of the artists' voices standing in for a voice actor's Zuckerberg impression and facial movements, he said.

But he said he also wants to raise questions about the creation of such media."People need to know it's possible to do it", he said. Instead of taking the video down, Facebook merely added some disclaimers to the video linking watchers to authentic sources on the issue.

A spokeswoman for Instagram said the fake video of Zuckerberg would receive the same treatment as the fake video of Pelosi and other misinformation. "If third-party fact-checkers mark it as false, we will filter it from Instagram's recommendation surfaces like Explore and hashtag pages".
